Flashcards in Inguinal Canal and Hernias Deck (18):
1

Umbilical hernias: in children

results from umbilicus not healing properly
heals itself spontaneously usually
usually smaller and wider transversely

2

umbilical hernias: in adults

results from weakness of abdominal wall around umbilicus
usually superior to umbilical scar
requires surgical repair
more common in women

3

Epigastric hernias

hernia of the linea alba
more common in men
requires surgery if large or symptomatic
occurs superior to umbilicus usually, but does not involve it

4

Floor of inguinal canal

inguinal ligament and lacunar ligament

5

Roof of inguinal canal

internal abdominal oblique fibers

6

Anterior wall of inguinal canal

External abdominal oblique

7

Posterior wall of inguinal canal

transversalis fascia and conjoint tendon

8

Beginning and End of inguinal canal

begins at deep inguinal ring around the midpoint of inguinal ligament and ends at superficial inguinal ring

9

the inguinal ligament is formed from

external abdominal oblique muscle

10

the superficial inguinal ring consist of the

medial, lateral crus and intracrural fibers

11

the lacunar ligament

an "extension" of the inguinal ligament
triangular in shape
apex at pubic tubercle
base is concave, lateral and sharp

12

pectineal ligament

posterior-lateral extension of lacunar ligament, runs along pectineal line

can form a sharp border that constricts the femoral hernia

13

Pouparts ligament

another name for the inguinal ligament

14

abdominal potential space

formed between scarpas and deep investing fascia of external abdominal oblique muscle

15

what is the abdominal muscle layer first encountered at the superficial inguinal ring?

external abdominal oblique

16

what abdominal layer is first encountered at the deep inguinal ring?

transversus abdominis

17

Incision hernias can occur at

surgical/laparotomy sites

18

Spigelian hernias can occur at

the semilunar line of the anterior rectus sheath
